This
is our high power series of single-ended 300B power amplifier, which
have totally the sweet and smooth airy sound of the small power version
of the 300B amplifier, and at the same time process the big dynamic
and high power driving capability. Now you don't need to use super
high efficiency speaker to work with your 300B but free to use whatever
speaker and still can fully utilize the super sweet character of this
tubes.

2.
300B is really for amplification of the music signal, not like some
others just use 300B in the power supply section and claim to be a
high power 300B amplifier

3.
no output transformers , so maximum damping factor and most widest
bandwidth can be achieved, the beautiful characters of the 300B is
totally exposed, the bass control and richness is so good that exceeds
any traditional 300B designs while the mid and high range sweetness
and silkiness still holds.

4.
Super low noise level, you will never hear such quiet background from
a traditional design single-ended 300B design

5.
No bias calibration , hum adjustment or any maintainence needed, the
300B tube works under a totally safe and long lasting operation conditions
which can almost last forever.

6.
Super low price per watt which you can get get from 300B tubes, typical
300B amp charge $500 per Watt , our design is only $38 per Watt for
standard version

2nd and 3rd set of photos show enhanced version with
tube recitier for $3,880 + $250

4th set of photos show enhanced version with dual
smartmon meter for $4,680

5th set of photos show SUPER version with enhanced
double-up power driving capabities as well as balanced inputs and
tube rectifier for $4,280 + $250

Any version add 5U4G tube rectifier and related circuits
for C$250 only

Option: Solid-oak chassis with black
top plate add $300

NEW
super enhanced version available with SMART monitor display (can display
as uV meter, scope and name plate) , XLR inputs, 6SN7 x 2, oil capacitors,
upgraded power supply and internal components, speaker protection
and start up delay circuits...etc, push every to limit just $4,680

SMART-Monitor
can change betweenNameplate
(whatever you want it to dispaly, we can progam it for you),VU meter , CRO,
MON ,HYPNO
and FFT mode, (details
check SMART-MON)
you can real time monitor the waveform and use this amp as a testing
equipment toward your other gears like a dual screen oscilloscope
or spectrum analyzer
